Application 'filed m 15,1sa4f, Nb 10am To all whom, zit may concern: Beit known that 1, Honey 9. ASERGEANT,

Statc'of New York, have invented a new and useful i'fiiipro venaentl in HoseCouplings, of which the following is a specification.

"My-invention relates to those couplings in which the end portionof the loose is slipped upon or overa shank or nipple, and there secured by a two-part ordivided clamp, which are inserted the bolts for thawing the partsof the hose, and in order to afford provision for jli iiceii'ing'inoicl'anip at any time the partsare" soiiormed; that they can never be" drawn com-' pletely together, as that would prevent any further tightening. Because oftliis peculiarity, the hose, when the clamp is applied, has

z t-ween the two-parts, and to thus prevent the tight clamping of the hoseiat such points, as

ing pinched between the said two parts oftbe clamp. I v

The object of myinvention-is to obviate the above-described diftioulty and to provide aclamp which will confine theliose so that it cannot bulge out between the two parts; and. to this end the invention consists in providing the parts of the clamp with lips or guards, which project eiroumferentially beyond the ears throngnwl ieh the tightening-bolts are insertefanii enter the other parts of the clamp. (lhese lips or guards bridge over or extend across the division or opening between the parts of tile clamp, and such a clamp will confine and clamp the hose around its entireoir cnniierence; Preferably each part ofthe clamp will provided at one side with a lip or oft-l e clamp may then be cast from thesame pattern, an; when reversed. the two lips or In tlie-aecom Jan in drawin' egfii nre l is sienna the dotted Fig, i; and Eig 3 wrench or spanner may b is a plan of one. of the two parts of the clamp employed, 1 I

Similar letters of reference designate correspending parts in ailtlie figures.

- AA, designate the-twoparts of the coupling, eac-lnoi which has along and. externallytap'ered shank, it, upon which nreslipped and seclurei the'two portions-B of nose to be connected. The part A ofithe coupling is pro video-with aprojecting flange, b, and-the part A." with an externally screw threaded flange or enlargement, b, and the two parts are con. nected by a swiveled not or Kern-band, C, hav- .i'ng an internal flange, 0, which engages.witli the flange bet the part A, and is capable of turning thereon to screw it upon-or unscrew it from the flangebof thepart Aof the coop 1 ring. IA packing; if, is placeilictwcen the flanges b b, and by turning up the'horn-band (J the said packing is clamped between the two parts to make a tight joint. The band or nut C is provided with horns 6, with which a,

e engaged for turning' the band or nut C.

The two sections ofhose B are slipped upon the taper shanks o of the parts A- A, and are there secured. each by atwo-part or divided clamp, D D,which are tightened upon the hose by ooltsf, passing through lugs or earsf,with' which the parts of the clamp are provided. Forward of that part of each shank a on which the hose B is slipped is an annular external enlargement, or, which is of about the same diameter as theliose after the clamp is applied, and in this enlargement is an annular groove or notch Thefiangeg; of the hornband C is internally' of. a size-to slip easily over the annular eni'argement a; but nonotches are necessary therein, as there are no projections beyond the cylind ric pcripl ery of the enlarge- ,m'cnt a.

The partsD of the clamp are provided with ibrwardlyprojecting books 9, which are preferably nearly semicircular in transverse section, and whiclnas the parts of-the clamp are iirawn together, pass into the groove or notches ano thereby hold. the clamp, and through a it the hose, from slipping off the shank a of the coupling.

' In order to prev'e out between the two parts if-$13.8 clamp, Ipro- Ioo nt the hose B and bulging tire clamp with lips-or guards h, which bulging out of the hose bebween t befitwo parts 11:1ojectbeyond he ears or. lugs f aim} eizier neat, ii, in' the opposite part, and, as we parts A The combinaiionfwibh :iconpiing, ofalzwothe opposite par-i of tho :iiamp'.

By the said lips or guards the of the clamp is prevented, and it is confined and clamped around its entire circumference. VVh'abI claim as my invention, and desire to secure bylethrs Patent, is-,
